Introduction

Measuring the concentration of hydrogen gas (H2) produced from the water electrolysis process is crucial for various applications, especially in the field of renewable energy. Hydrogen is a clean energy source that can be used as an alternative fuel. In this study, we aim to develop a tool that can measure the concentration of hydrogen gas in water using an Arduino-based MQ-8 sensor with an Android display.

Background

Water electrolysis is a process that splits water into hydrogen and oxygen gases. The concentration of hydrogen gas produced from this process is an important parameter that needs to be measured accurately. Traditional methods of measuring hydrogen concentration involve using expensive and complex equipment, which can be a limitation in many applications. In this study, we aim to develop a cost-effective and efficient tool that can measure hydrogen concentration using an Arduino-based MQ-8 sensor with an Android display.
